An auger-anchored beach umbrella has a canopy member for supporting the canopy and a pole member for anchoring the umbrella in the ground. The canopy member has a lower tubular element within which is formed an axial lumen. The pole member has an upper element which slides snugly into the axial lumen of the canopy member. The pole member has a motor element, within which is enclosed a reversible electric motor. Coupled to the motor's shaft is an auger. The motor is electrically connected to one or more batteries and to a switch. The user inserts the pole member into the ground by activating the switch in the forward direction, thereby causing the auger to bore into the ground. In the preferred embodiment, the user grasps a handle attached to the upper element to guide the pole member into the ground and to exert a supplemental downward force on it. After the auger is firmly anchored in the ground, the canopy member is mounted on the pole member by sliding the axial lumen over the upper element of the pole member. When the beach umbrella is removed from the ground, the canopy member is removed from the pole member. The user activates the switch in the reverse direction, thereby causing the auger to disengage from the ground. In the preferred embodiment, the user grasps the handle to guide the pole member out of the ground and to exert a supplemental upward force on it.

In another construction, a PTO collar provides several detents that interconnect with resiliently biased projections at an auger collar. A hand piece maintains the connection. In other embodiments, key(s) at the PTO shaft mate in non-rotational engagement with keyway(s) at an auger and a resilient member latches the non-rotational connection. Shaped PTO shaft surfaces and complementary auger coupler surfaces can be included with the later couplers to enhance the connection.

A control platform for directing the operation of a snowblower is provided. The platform includes a bail which is pivotably moveable within the platform. Attached to and moveable with the bail are levers for controlling the engagement or disengagement of the drives that power the snowblower's wheels and auger. Also attached with the bail are controls which permit the operator to change the speed and/or direction of the snowblower as well as the orientation of the discharge chute. Through their attachment to the bail and proximity relative to one another, an operator can use each of the levers and controls simultaneously. Accordingly, the platform permits an operator to engage or disengage the drives which power the snowblower's wheels and auger while, simultaneously, enabling a change in speed or direction as well as the direction towards which snow is directed during the removal process.

An auger airlock assembly and end dump housing having a spring loaded bottom for use in a bulk loader which utilizes a source of negative pressure to create a suction air stream that draws particulate materials into the loader for transfer, via the auger assembly, to a location remote of the loader. Materials exiting the auger assembly accumulate within the housing to a point wherein, once the accumulated material has acquired a certain weight, the bottom of the housing is forced open to permit discharge of the material, and, once the material is removed, and is not present in enough quantity to maintain the bottom of the housing to remain open, the spring loaded connection biases the bottom back into a position sealably closing the housing. The bottom of the housing may also be opened by the auger feeding more material into an already full housing, whereby the material is compressed so as to force the door open. Side portions of the housing limit the opportunity for outside air to enter the airlock assembly during the discharge of materials, maintaining the vacuum suction created by the negative pressure in the auger assembly.
